“The Black-veined White Butterfly”

Abstract

MY experience of this species in England enables me to support Mr. W. Warde Fowler's opinion (NATURE, February 14, p. 367) as to the preference of the spec es for open ground. I met with it in abundance in the New Fore t in 1866 1868, 1869, and 1870. It rarely occurred in or near dense woods, but preferred the open heaths and wastes of the Forest, where thistles were plentiful. In 1867 I found the species swarming, about midsummer, in hay fields on hill-sides in Monmouthshire. There were a few small orchards, but not much wood, in the neighbourhood. For a detailed account on the former distribution of Aporia cratægi in this country, I would refer Mr. Warde Fowler to my article on the subject in the Entomologists' Monthly Magazine for March 1887.
